I use bass.dll,BASSenc.dll(2.4.0.1) to develop a recording mp3 OCX with lame，but it not work on the PC that has bass.dll 2.3.0.2.
Now, I must replace bass.dll,BASSenc.dll  2.3.0.2 for my OCX，I don't find out this version files and sample in this website.
Please help me.   
Thank you for any help!

thanks you reply.
I regsvr32 my ocx file on different directory,including bass dlls(2.4 version) ,but other Applaction "B" use bass(2.3.0.2). My ocx base on "B" applaction, I can't change "B", because of not have source code file and It's complicated program.
What is a good way to solve it？

Hi

I guess you're using VB.

You can make it work with no matter how many BASS versions you have, by "telling" VB to load BASS and its add-ons from the specific directory inside your application directory, e.g:

1. Make a new directory by name "SoundSystem" (or whatever you like) inside your main application directory and copy all BASS dlls to that directory.
2. Change inside BASS.BAS - Lib "bass.dll" to Lib "SoundSystem\bass.dll"
   2.1. The same applies to any add-on you're using

btw, it doesn't work on other PC, because other BASS.DLL is inside windows\system32 directory.
The solution above will ignore BASS.DLL that inside system directory
